2. Informazioni sulla sicurezza

Please read and understand all safety instructions before installing or operating the CD-6H detector. Failure to follow these instructions may result in property damage, injury, or death.

• Installazione professionale consigliata: For optimal performance and safety, installation should be performed by a qualified professional in accordance with all local and national electrical codes.
• Disconnessione dell'alimentazione: Scollegare sempre l'alimentazione dal circuito prima di eseguire qualsiasi installazione, cablaggio o manutenzione.
• Non dipingere: Do not paint the detector. Paint can clog the sensor openings and interfere with the detector's ability to sense CO2.
• Posizionamento corretto: Install the detector in an area free from obstructions, excessive dust, high humidity, or extreme temperatures. Avoid placing near vents, windows, or doors that could affect CO2 readings.
• Test regolari: Test the detector regularly as described in the Maintenance section to ensure proper operation.
• Risposta all'allarme: Understand the meaning of the alarm signals and know how to respond safely to an alarm condition.

3. Impostazione

3.1 Disimballaggio

Carefully remove the CD-6H detector from its packaging. Inspect the unit for any signs of damage. If the unit appears damaged, do not install it and contact your supplier immediately.

3.2 Posizione di montaggio

Selezionare una posizione di montaggio che sia:

• Approximately 4-6 feet (1.2-1.8 meters) from the floor, at breathing level.
• Away from direct sunlight, heat sources, or air vents.
• Not behind curtains or furniture that could obstruct airflow to the sensor.
• In an area where the digital display and alarm indicators are easily visible.

3.3 Montaggio del rilevatore

1. Mark the desired mounting holes on the wall using the detector's mounting plate as a template.
2. Drill pilot holes if necessary and insert wall anchors (not supplied) if mounting into drywall.
3. Secure the detector to the wall using appropriate screws (not supplied). Ensure it is firmly attached.

3.4 Cablaggio

The CD-6H is a low voltage device. Refer to the wiring diagram provided with your unit for specific connection details. Ensure all wiring is done in accordance with local electrical codes and manufacturer specifications. Typically, the unit requires a stable DC power supply.

• Potenza in ingresso: Connect the appropriate low voltage DC power supply to the designated terminals.
• Uscite relè: If using the relay outputs for ventilation control or alarm systems, connect them as per your system requirements.
• Messa a terra: Assicurare una corretta messa a terra per evitare interferenze elettriche.

4. Istruzioni per l'uso

4.1 Accensione e riscaldamento

Once properly wired and mounted, apply power to the CD-6H. The unit will undergo a brief warm-up period, during which the digital display may show varying readings or a specific warm-up message. This process typically takes a few minutes. The green power indicator LED will illuminate.

4.2 Comprensione degli indicatori

• Display digitale: Shows the current CO2 concentration in Parts Per Million (PPM).
• LED verde: Indicates normal operation and power supply.
• Red LED / Audible Alarm: Activates when CO2 levels exceed the preset alarm threshold.

4.3 Risposta all'allarme

If the alarm activates (red LED illuminates and audible alarm sounds):

1. Niente panico.
2. Immediately move to an area with fresh air.
3. Ventilate the area by opening windows and doors, if safe to do so.
4. Identify and address the source of elevated CO2.
5. Do not re-enter the affected area until CO2 levels have returned to safe limits and the alarm has ceased.

4.4 Calibrazione automatica

The Macurco CD-6H features an auto-calibration function, which automatically adjusts the sensor's baseline over time to compensate for drift. This feature helps maintain accuracy without requiring manual calibration in most typical environments. Refer to the full technical manual for details on manual calibration procedures if required for specific applications.

5. Manutenzione

Regular maintenance ensures the longevity and accurate operation of your CD-6H detector.

• Pulizia: Pulire delicatamente l'esterno del rilevatore con un panno morbido eamp cloth. Do not use harsh chemicals, abrasives, or solvents. Ensure no liquid enters the sensor openings.
• Rimozione della polvere: Periodically, use a soft brush or a vacuum cleaner with a brush attachment to remove any dust or debris from the sensor openings.
• Test funzionale: It is recommended to perform a functional test periodically (e.g., monthly) by exposing the sensor to a known source of CO2 (e.g., exhaled breath from a distance, or a CO2 test gas if available) to verify alarm activation.
• Durata del sensore: While the CD-6H features auto-calibration, all gas sensors have a finite lifespan. Consult the manufacturer's specifications for expected sensor life and replacement recommendations.
